SLIDING-SASH WINDOW.

Application filedDece'mber 29, 1920. Serial No. 433,768.

To all whom it may concern Be it known that I, JACOB zen of Germany, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Sliding-Sash Windows, of which the following is a specification.

My invention relates to Windows of the siiding-sash type, and is a further development of the construction disclosed in my copending application for Letters Patent Serial No. 401,372, filed in the United States Patent Oflice on August 5,1920. The object of my present improvements is to $1111 plify the construction shown in said earlier application and to secure certain advantages in operation, as will appear from the description following hereinafter.

A preferred embodiment of my present invention is illustrated by the accompanying drawings, in which Fig. 1 is an elevation of the complete window as seen from the inside, with the sashes in the closed position; Fig. 2 is a vertical section of the window frame, the sashes being omitted; Figs. 3 and 4am enlarged horizontal sections on lines 33 and '44 respectively of Fig. 1; Fig. 5 is a. view somewhat similar to Fig. 2, but showing the sashes in position, with the lower sash swung inward for ventilation; Fig. 6 is a similar view showing the lower sashraised and the upper sash lowered and swung inward; Fig. 7 is a horizontal section on line 77 of Fig. 5; Fig. 8 is an enlarged face view showing a lower corner of the lower sash with a looking and pivot bolt attached thereto; Fig. 9,

the lower sash being shown in tight engagement with the upper sashq Fig. 12 shows the frame parts in substantially the same position as in Fig. 10, but the upper sash is shown down, and the. lower sash up; Fig. .13 is a vertical section on line 1313 of 12 {and Fig. 14 is apartial view from above,

looking at the lower. sash in thedilection a v 4 I a V calgrooves 45. adapted to receive edgewi'se, metal strips 46 suitably secured to the strips of the arrow 14 in Fig. 5. The window frame llustrated herenrcon Wiiniin, a citiv prises a bottom member 20, vertical boxes 21,

22 ateach side which contain the sash weights 23, an upper member 24 at the outer slde of the window, and a horizontal box or chamber 25 at the top, on the inner side of the window, the lower edges of said box being flush with the upper edges of the opposln 22. ward the outside of the window, relatively wide vertical strips 26 extending the full height of said walls, and on the opposing faces of the strips 26, at their outer edges, are secured narrower strips 27, likewise ex-. tending the full height of the walls 21 22'. Along the inner edges of said walls, at the upper portions thereof, aresecured vertical strips 28 and at the lower portions thereof movable vertical strips 29 "(for instance strips mount-ed on vertical hinges30) which in one position (Figs. 1,3, 6, and 10 to 13) will lie in the continuation of the upper;

strips 28, while in another position (Figs.

2, 5 and .7 and dotted lines in Fig. 3) they will be out ofthe way so as to clear the path for the inward swinging of the lower sash, as described hereinafter. When thus (I walls 21, 22 of the side boxes 21, 6n said opposing walls are secured, tol aligned, the strips 28, 29 form the inner walls of the .guideways for the "lower sash 31,'the outer walls of said gnideways being formed by the strips 26, and'the side walls byparts of the members 2l,"22. "At the sides, toward the outside of the window, the vertlcal members of thelower sash are rechambers to receive the cords or chains passing over the corresponding pulleys 34 to ends of these chains are secured to plates 35 pivoted at 36 to the side members .37 of a:

the respective sash weights 23. The lower L-shaped plates' secured to the lower sash 31 near its bottom corners. The inner members 38 of said L-shapedplates have aligning horizontal slots 39 (see Figs'l and 8) in which are movable studs 40 rigid with transversely movable pivot and locking bolts 41 adapted'to be projected into recesses42 of the walls 21', 22.

At is" bottom, the lower sash 31 has a transverse groove 43 which is adapted to contain a rounded horizontal bar or strip 44 projecting from the bottom member 20. On its rear face, the sash 31 has two verti- 1 t si l as t ev ee rt oe h rea When the lower sash 31 is moved up, its rear face will be guided partly by the strips 26,

and partly by narrowstrip Or'beatls 47 gel cured to theopposing faces "ofthe strips 26, at their upper portions only. The strips 46 and 47 overlap partly, as shownbest'in Fig. 2.

In the box or chamber is movable vercally? orizenta b ard e8, mende at its end with notches guided along vertical ridges 49. In its normal position (Figs. 2

and 5),' said boardrests on the upper ends of the Walls 21', 22 and of the strips 47.

n the n e s de o the w n w, t a sms rom e ba r tr 4 ii l e the path of the lower sash 31, is locateda horizontal strip 50 secured to the bottom member 20. At the upper end or the lower sash 31 is located the herizonth m ans 1 rail.

' wardly frorn the strips 27 into vertical grooves in the outer face of the upper sash 58. -At its upper edge said sash" has a. groove 60 similar to the groove 43,"and adapted tofit a horizontal top bar 61 siinilar tothe' bar 44 The "sash 58 is cut' ou t, as at 62,- to form channels the ohains 63 whiclrare attached at the "bottom of the sash in the same way as the'chains 33 and P O pul y the eer e s sash weights 65. It will be seen (see Fig. 4) that the upper sash is narrower than the space between the two stripsl6; and maytherefore swing betweenthem as eziplained ei At ts 9Wer. edge the pp s esh' f fully down (in contact" with the bottom has a meeting rail 66 with an inclined 1S9? face adapted to engage the corresponding surface of the meeting rail 51 of the lower sash (Fig 1'1').' The upper sash also has a plate 67 projecting inwardly at the bottom ofthe'mee'ti-ng rail 66 and adapted'to engage the horizontal lower surface of the. meeting rail 51. The panes of the sashes 81 and 58 are designated by 68 and 69 respectively. At its lower end, each of the strips 47 has a vertical slot 70 (Figs. 10, 12 and 13) in which is adapted to slide up and down a stop member 71, provided with an upright slot 72 through which extend the stationary pins 73. These pins in connection with the slot limit the movement ofthe stop 71 in both directions, the upper inactive position being shown in Fig. 10 '(see also dotted lines in lfigs. 11 12) while the lower operative position of the stop is shown in Figs. 12 and 13. The lower ends 74 of the two stops 71 may be bent horizontally, toward oth r the normal closed position of the window 1) the upper sash 58 malres'a tight or'at least windproof joint with the bar 61 at the groove 60. Similarly, the lower sash 31, at its bottom, has a windproof joint where the bar 44: projects into the grooves 43 of said sash, and the strip '50 furnishes an additional barrier engaging the inner face of the sash at its bottom. The board 48 is in its lower position shown in 2 and 5, and thus oonceals'the existence of the cavity or chamber 95; this board might be omitted, since its only purpose is to conceal the unsightly opening at'the bottom ofthe chamber 25 which would other- Wise be exposed toview whenever the lower sash has its top below said chamber. With J the window closed, the meeting rails 51, 66 and the plate 67 are in engagement as in Fig. 1 1, so as to secure a tight'joint at this point also. The locking boltseil are retracted (Fig. 12), so as to leavethe lower sash 3 1 free to move up and down, and the stop nernbers 71 are in their raised position full lines in Fig. 10, and dotted lines in *igs. 11 and 12). I may here remark that the mere act or" raising theupper sash to the closed position will cause the stop illGlllbers71to be raised by contact with the plate 67', the-meeting rail 66 being cut at each side (see Fig. l0) so as'to clear the stop member 71 and the strip lnth'e particular embodiment illustrated, the rais ing of the upper sash 58 to its uppermost position will not bring the stop members ,71 entirely to the uppermost position shown, but a slight additional upward movement willhave to be givento thestop members 71 manually. tobring them to their uppermost or releasi-ngposition. This releasing position issuch that when the upper sash 58 is member 20) this being the position shown in plate 67 at the'top and the normally outer surface of the pane facing toward the inside of the building. It will be noted that this inward swinging of the upper sash 58 can be effected without. bringing the hinged strips 29 out of their normal position (Fig. 3). This is possible for the reason that the upper sash 58 is narrower than the space between the two strips 29, as will be obvious from Figs. 3 and 4.

In order to enable the upper sash 58, when fully lowered as just described, to be swung inwardly, the lower sash 31 must be raised to a position (Figs. 6, 12 and 13) in which it clears the path of the upper sash 58 for such inward swinging. The chamber 25 is provided for the purpose of giving the lower sash 31 the extra upward travel re quired to accomplish this result. In bringing the sash 31 to this position, Fig. 6, the board 48 is raised by the upper edge of the sash, but as soon as the sash is lowered, the board 48 will drop back to the normalposition shown in Figs. 2 and 5.

When it is desired to clean the inner surface of the pane 69, the upper sash 58 is is raised fully, its plate 67 will raise the stop members 71 somewhat, but not fully, so that manual operation, as described above, will be required to bring the stop members to the releasing position Figs. 10 and 11.

The inner surface of the pane 68 of the lower sash 31 will be cleaned in the usual manner. To clean the outer surface of said pane, the hinged strips 29 will be swung open as indicated in Fig. 5 (see also dotted lines in Fig. 3 and at the left of Fig. 7), thus clearing the path for the inward swinging of the lower sash (when in its lowermostposition) in the same manner as described above with reference to the upper a pivot, until the sash is about horizontal. with the outer surface of the pane 68 on top;

or, together with such swinging movement,

the lower edge of the sash may he slid upward until the sash 31 is vertical, but inverted, with the normally outer surface of the pane 68 facing inward. hen it is desired to open the lower sash 31 slightly, for ventilation, as shown in Fig.

5, the said sash being in its normal lowered position, the ball-shaped enlargement of the bar 54 is introduced into the wide end of the key-hole slot 56 and swung laterallytherein to the other end of said slot. The sash 31 may then be opened within thelimit permittedby the maximum extension of the opened for ventilation, or into a substan tially horizontal position for cleaning, the,

two locking and pivot bolts 41 are projected as in Fig. 8 and engaged with the recesses 42.

Various modifications may be made without departing from the nature of my invention as set forth in the appended claims.

I claim:

1. In a window, a relatively wide sliding sash and guides therefor, a relatively narrow sash adapted to pass between the guides of the first-named sash when the latter is in one of its extreme positions, means for freely suspending said sashes pivotally connected upon a horizontal axisto the lower extremities of said sashes, and guides for the second-named sash, terminating in a position which permits said sash when moved upon its pivotal connection to freely pass between the guides of the first-named sash when the two sashes are in opposite extreme positions, whereby said second named sash may be entirely reversed upon its pivotal connection without removing said first named sash.

2. In a window, a frame having continuous upright outer guide strips and strips projecting inwardly from said guide strips at their upper portions only, middle guide strips facing said outer guide strips at said and extendingv therefrom down to the bot-z tom of the window opening, inner guide strips facing said middle guide strips and said additional projecting strips, the lower portions of said inner guide strips being.

movable to leave a. clear space under their upper portions, and a lower sash movable between said inner and middle guide strips and having grooves in its outer surface to receive said additional projecting stiip' s,thje height of said lower sash being less than the length of said movable portions ofthe inner guides. 8. In a window, a frame having continuous upright outer guide strips and strips projecting inwardly from said guide Strips at their upper portions only, middle guide strips facing said outer guide strips at said upper portions only, an upper sash arranged to travel in engagement with the opposing faces of said outer and middle guide stri'ps, and having grooves in its outer surface to receive said projecting strips, the height of said sash being less than the distance from the lower end of the middle guide strips to the bottom ofthe window opening, additional strips projecting inwardlyifmm the lower portions of the middle guide strips and extending therefrom down to the bottom of the window opening, inner guide strips facing said middle guide strips and said additionalprojecting strips, the lower portions of said inner guide strips being movable to leave a clear space under their upper portions, the distance between theinner guide strips being greater than the width of the upper sash, and greater than the distance between the middle guide strips, and a lower sash, wider than the upper sash, movable between the said inner and middle guide strips and having grooves in its outer surface 'to receive said additional projecting strips, the height of said lower sash'being less" than the length of said movable lower portions of theinner guides.

In testimony whereof I have affixed my signature.

JACOB WEBER.
